You're welcome!

Quick addition: after sending my previous e-mail I kept browsing around
the Haiku website, and it looks like one of the ideas for this year's
Google Summer of Code is precisely migrating to WebKit2. You can see the
full list of GSoC ideas here:

  https://www.haiku-os.org/community/gsoc/2019/ideas

Maybe you will want to apply, but at least you can see there that there
is one contact person (IRC: PulkoMandy) who would be mentoring the porting
effort, so I suppose it would be good to contact them to coordinate :)

Cheers,


-Adrián
